With an absence of good disposal options for vactor and sweeping trucks, finding safe and responsible disposal options for material without mixing waste is challenging. GRT offers municipalities simple and conscientious solutions for slurry waste.s.
The problem: A large development is under construction at an excavated site. Water collects in the work site which stalls progress until dewatering can be completed. The client wanted to discharge water into the storm drain that feeds into local streams which are a salmon habitat. Due to the high sediment levels in the water, this client required a treatment process to reduce TSS loading because of detrimental harm to aquatic life.
Solution: We designed and installed a physicochemical treatment to remove solids and produce clean effluent safe to discharge. Weekly site visits and regular testing from our team ensure the system is performant.
Coagulation, flocculation, settling tanks, sand filtration to capture remaining solids, and clean water can be discharged directly down the storm drain.
